Which of the following would be a reason for a postal employee to reference a handbook?

Referencing a handbook, particularly in the context of postal operations, is essential for employees to gain a comprehensive understanding of the procedures and workflows in place, such as manual sorting systems. Handbooks are often specifically designed to provide details on standard operating procedures, job responsibilities, and guidelines that employees need to follow. By consulting the handbook, a postal employee can familiarize themselves with the technical aspects of sorting mail manually, including the classification of mail types, sorting mechanisms, and how to efficiently handle mail in accordance with postal standards.

This resource is crucial for ensuring that employees perform their tasks accurately and efficiently, adhering to established protocols that affect overall operational effectiveness. While other options may involve important aspects of the postal business, they do not directly relate to the primary procedures and systems detailed in the handbook, which serve as a vital point of reference for job-specific inquiries and training.
